Evaluation of Minimum Longitudinal Reinforcement Requirements for Reinforced Concrete Columns
Size: 2.3 MB | Format:PDF
Existing minimum longitudinal reinforcement requirements for columns were developed to prevent passive yielding of reinforcement resulting from creep deformations in the concrete. Tests used to support this limit were conducted decades ago when steel yield strengths for reinforcing bars were approximately half of what is common today. The design of a very large percentage of columns in TxDOT bridges is typically controlled by minimum eccentricity of loads, implying a substantial reduction in column steel and resulting economic savings might be possible with present-day materials.

This book could be an excellent reference for the researchers and engineers who work on the performances of pile and pile groups under lateral loadings such as earthquakes, ship collisions, water waves and currents, etc.
Could anyone please offer the link for this 2nd edition? Many thanks !!

Handbook 2 - Design of Timber Structures According to EC 5
Size: 1.9 MB | Format:PDF | Publisher: Leonardo da Vinci Program | Year: 2008 | pages: 138
This handbook makes specific reference to design of timber structures to European Standards and using products available in Europe.
The handbook is closely linked to Eurocode 5 (EC5), the European code for the design of timber structures. For better understanding of the Eurocode 5 design rules the worked examples are presented.
The purpose of this handbook is to introduce readers to the design of timber structures. It is designed to serve either as a text for a course in timber structures or as a reference for systematic self-study of the subject.

Abstract
Covers detailed aspects of internal floor finishes, including staircases, in non-domestic buildings. It covers general design issues common to most types of flooring as well as particular requirements for specific locations such as entrances, kitchens and sports halls. Operation and maintenance issues, including cleaning, that need to be considered at the design stage are also indicated. Advises in the context of the Disability Discrimination Act 1995 (DDA).

Tuned liquid dampers are cost effective dynamic vibration absorbers that are increasingly being employed to mitigate the dynamic response of tall buildings. A significant reduction in the dynamic response of a tall building can be achieved if the TLD is properly tuned and has sufficient inherent damping. The required level of TLD inherent damping can be obtained by installing damping screens inside the TLD tank. This paper develops an equivalent linear mechanical model that accounts for the energy dissipated by the damping screens. Equivalent linear damping ratio expressions are developed for both sinusoidal and random excitation. An equivalent linear mechanical model is subsequently developed using an equivalent displacement variable and the linear damping ratio corresponding to the type of excitation being applied to the structure. Experimental tests are conducted on a scaled model structure-TLD system subjected to both sinusoidal and random excitation to validate the proposed model. Comparisons are made between predicted and measured structural response motion and TLD free surface response motion over a range of structural response amplitudes. A preliminary design procedure for initial TLD sizing and initial damping screen design for a TLD equipped with damping screens is outlined.
